CraftCopper is 1.75mm copper-infused PLA filament and comes in half kilogram spools. It works well with CraftBot 3D printers, as well as other 3D printers that print with 1.75mm filament. Models printed using CraftCopper filament are heavier than those 3D printed with standard PLA, and feature a unique texture that can be sanded and polished for a metallic finish, or rubbed with steel wool to create a worn metal appearance.
